It looks like there may be some truth to those Jay-Z and Justin Timberlake tour rumors. The first piece of evidence comes in the form of an upcoming performance from the duo to headline the 2013 Wireless Festival in London.

The two day event kicks off July 12th. On the first day, performers include Frank Ocean, John Legend, Miguel, Snoop Dogg, Trey Songz and Justin Timberlake. The following night Calvin Harris, Kendrick Lamar, DJ Fresh, Emeli Sande, Miguel and Rita Ora will hit the stage before the “Suit & Tie” collaborators close out the festival with a bang.
